Glue at parent nameservers
0/7

WARNING
The parent servers are not providing glue for all your nameservers. This means that they are supplying the NS records (host.example.com), but not supplying the A records.
That may cause some extra milliseconds in DNS. This will usually occur if your DNS servers are not in the same TLD as your domain

NS

Mismatched glue

Skip glue checking. Make sure the nameservers domain is good standing
Check worldnic.com

SOA

SOA record

SOA record is:

Hostmaster email

namehost.WORLDNIC.COM

Serial

117102016

Refresh

10800

Retry

3600

Expire

604800

TTL

7200

Serial agreement
7/7

SUCCESS
All your nameservers agree that your SOA serial number is 117102016 That means that all your nameservers are using the same data.

SOA MNAME
3/3

SUCCESS
SOA (Start of Authority) record states that your master (primary) name server is: NS33.WORLDNIC.COM That server is listed at the parent servers, which is correct.

Serial value
0/1

WARNING
SOA serial number is: 117102016 This not appears to be in the recommended format of YYYYMMDDnn, where 'nn' is the revision. This number must be incremented every time you make a DNS change.

Refresh value
1/1

SUCCESS
SOA Retry interval is : 10800 seconds. This seems OK. (Values about 3600-7200 seconds is good if not using DNS NOTIFY; RFC1912 2.2 recommends a value between 1200 to 43200 seconds (20 minutes to 12 hours)). This value determines how often secondary/slave nameservers check with the master for updates.

Retry value
1/1

SUCCESS
SOA Retry interval is : 3600 seconds. This seems OK. (Values about 120-7200 seconds is good). The retry value is the amount of time your secondary/slave nameservers will wait to contact the master nameserver again if the last attempt failed.

Expire value
1/1

SUCCESS
SOA Expire time is : 604800 seconds. This seems OK. (Values 604800 to 2419200 seconds (1-4 weeks) is good). RFC1912 suggests 2-4 weeks. This is how long a secondary/slave nameserver will wait before considering its DNS data stale if it can't reach the primary nameserver.

TTL value
1/1

SUCCESS
SOA Expire time is : 7200 seconds. This seems OK. (about 300 to 86400 seconds or 5 min - 24 hours is good). RFC2308 suggests a value of 1-3 hours. This value used to determine the default (technically, minimum) TTL (time-to-live) for DNS entries, but now is used for negative caching.
